Driving connection for lace making machines



DRIVING CONNECTION, FOR LACE MAKING MACHINES Filed June 1, 1935ITNESSES: INVENTOR: v I MMUPM EHLEfi Patented June 16, 1936 UNITEDSTATE5 PATENT OF IVING CONNECTION FOR LACE MAKING MACHINEs 5 Claims.

This invention deals with the art of lacemak: ing machines, and isconcerned particularly with certain driving connections employed inconjunce wi h the qua d eehtrel whi h rdina i is n l n a em hihe m chineA le ne mach ef eenven ene desieh ordinarily includes a bed in which isoperatively mounted a u ality of shaft f r sent e hhe a ng ra ons on hepart o he s i dl which rry h thr ad.- The c nt i funcions are ef c d bylehe udihe-l movemen hi the s s ac o e e of the'mac ne and t s invent onhas in v w, as its primary obj c the Die isie of d i in onn ctio s hetwh th jacquard control, and these shafts in the bed, whershyadjacentshafts are rendered simultaneously and yet independently operable.

More particularly, this invention contemplates a driving connectionwhich provides for a depressing of a pair of adjacent shafts, whichdriving connection will, at the same time, permit either shaft to bedepressed while the next adjacent shaft is maintained in its normalupraised position.

A detailed object of the invention is to provide in a driving connectionof the character noted a member which is carried by arms extending fromthe shafts to move the shafts together in one direction, but whichmember is movable relative to either arm so that its respective shaftmay be depressed independently of the next adjacent shaft.

These and other more detailed objects and advantages will in part becomeapparent, and in part be hereinafter stated.

The invention, therefore, comprises a plurality of shafts fromwhichextend arms, said arms being formed with recesses, cross piecesextending across adjacent arms and received in the recesses, andoperating links extending from the cross pieces to the jacquard control.

For a full and more complete understanding of the invention, referencemay be had to the following description and drawing of the invention,wherein:

Figure 1 is a fragmentary plan view bringing out the disposition of theplurality of shafts and the driving connections therefor,

Figure 2 is a side view partly in section and partly in elevation, andwith parts broken away, bringing out the said driving connections, and

Figure 3 is an enlarged detail view bringing out the rocking of thecross pieces.

Referring now to the drawing, wherein like reference characters denotecorresponding parts,

Referring now to Figure 2, it is noted that each of the shafts I0 isprovided with a collar l2 and a coil spring l3 disposed about each ofthe shafts Iii, and it is retained between the collar l2 and the bed i Iof the machine. These springs I3 normally maintain the shafts ID in anupraised position in which abutments, shown at M, engage the lower faceof the bed I I. At their lower ends each of the shafts I9 is providedwith a pair of arms designated l5, which are drivably connected to theshafts In by the connection comprising hub portions l6 and set screwsI1.

Referring particularly to Figure 1, it will be noted that the arms i5carried by each of the shafts ID are disposed in an angular relationwith respect to one another. At their extremities each of the arms In isenlarged to provide a portion having a recess I8, the recesses l8 inadjacent 3.5 arms together defining what is in effect, a unitary socket.

A cross piece [9 is received in the socket defined by adjacent recessesl8, and connected to the cross piece l9, centrally thereof, is a link 20which at its lower end is connected as indicated at 2| to a bell crank22 that is mounted on the frame of the machine, which frame isdesignated 23, and which bell crank is connected to the jacquardcontrol, as indicated at 24. It is noted that the link 20 is connectedto the cross piece I9 by a hook member 25 that extends between theextremities of the arms l5, which hook member is anchored in the middleof the cross piece l9.

Referring now particularly to Figure 2, the operation of the abovedescribed driving connection may be briefly described as follows. Withthe parts in the position illustrated, it is evident that either one ofthe shafts It may be lowered, with respect to the bed H, in which eventthe arm l5 of the shaft being lowered, is merely withdrawn from thecross piece 19, in which event the latter rocks slightly, but isretained in the socket in the recess I8 of the adjoining cross piece, asindicated in Figure 3.

If both of the shafts ID are to be lowered against the influence of thesprings [3, a pull on the connection 24 will be transmitted through thebell crank 22 to cause the ring 20 to pull the cross piece I 9downwardly, whereupon both of the arms carrying the cross piece l9 willbe moveddowm wardly, and corresponding movement is imparted to therespective shafts l0.

However, by this same driving connection being availed of between eachofthe adjacent arms l5, movement of the latter downwardly will notaffect any other of the shafts, it being only the movement of the crosspieces I9 downwardly which has this effect.

While a preierred specific embodiment of the invention is hereinbeforeset forth, it is understood that I am not to be limited to the exactmechanisms illustrated and described, as various modifications of thesedetails may be provided in putting the invention into practice, withinthe purview of the appended claims.

I claim:-- 7

1. In a lacemaking machine, a pair of shafts, arms extending from eachof the shafts, said arms having recesses in their extremities, saidrecesses defining a socket, a cross piece in the socket, and a linkconnected to said cross piece.

2. In a lacemaking machine, a pair of shafts, arms extending from eachof the shafts, said arms having recesses in their extremities, saidrecesses defining a socket, a cross piece in the socket, a linkconnected to said cross piece, and means for operatively connecting thelink to a jacquard control.

3. In a lacemaking machine, a bed, a plurality of shafts disposed insaid bed for vertical movement with respect thereto, a jacquard control,and driving connections between the jacquard control and the saidshafts, said driving connections including two independent connectionsto each of said shafts, either of which may be rendered effective tomove the shaft at the same time rendering the other connectionineffective. 4; In a lacemaking machine, a bed, a plurality of shaftsdisposed in said bed for vertical movement with respect thereto, a pairof arms carried by each of said shafts, each arm of each shaft extendingtowards similarly extending arms of adjacent shafts, a jacquard control,and driving connections between the jacquard control and said arms, eachdriving connection being connnon to the arms extending from adjacentshafts.

5. In a lacemaking machine, a bed, a plurality of shafts carried by thebed in vertical position and movable with respect thereto, yieldablemeans normally maintaining said shaft in upraised position with respectto the bed, a pair of arms carried by each of said shafts on theunderside of the bed, a jacquard control, and connections between thejacquard control and arms whereby either arm maybe constituted aneffective connection for moving the shaft to which itis directeddownwardly against the influence of the yieldable means.
